Diffusion and Osmosis

Question 1

Turgidity meaning

Answer 1

The state of being turgid or swollen due to high fluid content. When water has moved in via osmosis.

Question 2

Plasmolysis meaning

Answer 2

The shrinking of protoplasm away from cell wall due to water loss from osmosis. Results in gaps between cell wall and cell membrane.

Question 3

Diffusion meaning

Answer 3

Passive transport of the movement of particles from high concentration to low concentration until equilibrium of concentration.

Question 4

Osmosis meaning

Answer 4

Special type of diffusion. Active transport of water molecules that move through a selectively permeable membrane from a solution of low concentration to high concentration thereby diluting it. Occurs until equilibrium of concentration of solutes.

Question 5

Why turgidity is important for plants?

Answer 5

Turgidity is essential in plant cells to make them keep standing upright. Plant cells that lose too much water have less turgid pressure and tend to become flaccid.
